This study is conducted to analyse the process and the pattern of motivation for musical expression in clinical music therapy for the adults in the mental health center. The participant were 8 adults purposive sampling who had more than one year music therapy experience in the mental health center and their age ranged from 27 to 53. A major category derived and analysed from the grounded theory method by Strauss and Corbin. The qualitative analysis indicated that motivation for musical expression in music therapy, which was the central phenomenon in this study, was determined by the music therapist and songs used in the sessions. The central phenomenon was caused by the therapist's friendly attitude, high musical capacity, the familarity of the selected songs and the significancy of the lyrics of selected songs. The levels of reliability about the therapist's personality and musical ability as a professional music therapist and the positive arousal of the songs used in sessions affected as the contextual condition. Spontaneous musical expression in music therapy brought the escape from reality, release of stress and sharing by the intervening condition 'empathy' and this resulted in mood regulation, the instillation of hope and group cohesion. It has been found that there were three types of motivation in music therapy: intrinsic motivation, relationship dependent extrinsic motivation and evasive motivation.

The cyclopentenone prostaglandins (cyPGs) prostaglandin $A_1$ ($PGA_1$) and 15-deoxy-${\Delta}^{12,14}$-prostaglandin $J_2$ (15d-$PGJ_2$) have been reported to exhibit antiinflammatory activity in activated monocytes/macrophages. However, the effects of these two cyPGs on the expression of cytokine genes may differ. In this study, we investigated the mechanism of action of $PGA_1$ in lipopolysaccharide (LPS)-induced expression of inter leu kin (IL)-10 mRNA in mouse peritoneal macrophages. 15d-$PGJ_2$ inhibited expression of LPS-induced IL-10, whereas $PGA_1$ increased LPS-induced IL-10 expression. This synergistic effect of $PGA_1$ on LPS-induced IL-10 expression reached a maximum as early as 2 h after simultaneous $PGA_1$ and LPS treatment ($PGA_1$/LPS), and did not require new protein synthesis. The synergistic effect of $PGA_1$ was inhibited by GW9662, a specific peroxisome proliferator-activated receptor ${\gamma}(PPAR{\gamma})$ antagonist, and Bay-11-7082, a NF-${\kappa}B$ inhibitor. The extracellular signal-regulated kinases (ERK) inhibitor PD98059 increased the expression of $PGA_1$/LPS-induced IL-10 mRNA, rather than inhibiting the IL-10 expression. Moreover, $PGA_1$ inhibited LPS-induced ERK phosphorylation. The synergistic effect of $PGA_1$ on LPS-induced IL-10 mRNA and protein production was inhibited by p38 inhibitor PD169316, and $PGA_1$ increased LPS-induced p38 phosphorylation. In the case of stress-activated protein kinase/c-Jun $NH_2$-terminal kinase (SAPK/JNK), the SAPK/JNK inhibitor SP600125 did not inhibit IL-10 mRNA synthesis but inhibited the production of IL-10 protein remarkably. These results suggest that the synergistic effect of $PGA_1$ on LPS-induced IL-10 expression is NF-${\kappa}B$-dependent and mediated by mitogen-activated protein (MAP) kinases, p38, and SAPK/JNK signaling pathways, and also associated with the $PPAR{\gamma}$ pathway. Our data may provide more insight into the diverse mechanisms of $PGA_1$ effects on the expression of cytokine genes.

Underground structures such as a tunnel have been considered as safer than structures on the ground during earthquake. However, severe damages of underground structures occurred at subway tunnel during 1995 Kobe Earthquake and such damages are gradually increased. In this study, a dynamic behavior of a cut and cover tunnel surrounded by weathered soils is investigated using Mohr-Coulomb Model. Parametric study was carried out for boundary conditions, tensile strength, and earthquake magnitudes. The results of numerical analyses in terms of ground deformations and stresses acting on the lining were quite dependent on the side boundary condition (free or fix conditions) and tensile strength of surrounding soils. The ground was deformed upward at the end of earthquake when the side boundary condition was fixed, whereas residual deformations were not predicted when it was free. When the tensile strength of a soil was set to the same as its cohesion, residual deformation was less than 1cm, regardless of side boundary conditions or input accelerations. In addition to that, stress conditions at the maximum deformation and end of earthquake were within an allowable range and considered as safe. Proper boundary conditions and material properties such as tensile strength are quite important because they may significantly impact on the results of dynamic analyses.

No other change in Kora has offered gredter chalenges and opportunities than the emergence of the Internet and its related Information Technology. In the technology for accessing the ever growing wave of information. The quality of the silver generation is increasingly difficult to achieve because of the complexities of life in today's ICT(Information & Comunication Technology) dependent society, Life is more interesting when one knows what is going on, what opportunities exist, and when alternatives to current practices can be discovered and utilized with ease. The purpose of this study is to identify the determinants of attitude and planned behavior toward using internent for the quality of life. This study employ the intention to use internet, perceived ease of use, perceived usefuiness, self-efficacy, stress factor, generation gap, and income as major research variables, and collected 288 survey responses from senior citizen over 55. The results indicate that the perceived usefuiness and ease of use influence the intention to use internet, and that the self-efficacy, the ease of use and generation gap has some impact on the attitude, but the stree factor and the income level do not appear significant to the attitude. It was also found that the self-efficacy and the income level determine the level of ease of use. In addition, some useful suggestions concerning the continuing education program for silver generations are presented.

$Schizandra$ $chinensis$ Baillon is a traditional folk medicine plant that is used to treat and prevent several inflammatory diseases and cancer in Korea, but the underlying mechanisms involved in its anti-allergic activity are not fully understood. This study was designed to investigate mechanisms of anti-allergic activity of a $Schizandra$ $chinensis$ Baillon water extract (SCWE) in immunoglobulin E (IgE)-antigen complex-stimulated RBL2H3 cells and to assess whether gastric and intestinal digestion affects the anti-allergic properties of SCWE. Oxidative stress is an important consequence of the allergic inflammatory response. The antioxidant activities of SCWE increased in a concentration-dependent manner. RBL-2H3 cells were sensitized with monoclonal anti-dinitrophenol (DNP) specific IgE, treated with SCWE, and challenged with the antigen DNP-human serum albumin. SCWE inhibited ${\beta}$-hexosaminidase release and expression of interleukin (IL)-4, IL-13, and tumor necrosis factor-alpha (TNF-${\alpha}$) mRNA and protein in IgE-antigen complex-stimulated RBL2H3 cells. We found that digested SCWE fully maintained its antioxidant activity and anti-allergic activity against the IgE-antigen complex-induced activation of RBL-2H3 cells. SCWE may be useful for preventing allergic diseases, such as asthma. Thus, SCWE could be used as a natural functional ingredient for allergic diseases in the food and/or pharmaceutical industries.

This study was to investigate the antioxidant, anti-inflammatory and neuronal cell protective effects of Poria cocos Wolf and Corni fructus extracted by water and 70% ethanol. Total polyphenol content in water extract of Poria cocos Wolf was significantly higher than those of other extracts. DPPH and ABTS free radical scavenging activity in water extract of Corni fructus was higher than those of other extracts. DPPH and ABTS free radical scavenging activity were increased in a dose-dependent manners. In order to effectively extract total polyphenol contents and anti-oxidant components in Poria cocos Wolf and Corni fructus, hot water extraction method is more efficient than ethanol extraction method. Poria cocos extracts were found to be a superior NO production inhibitory effect compared to Corni fructus extracts. In a neuronal cell viability assay using MPP⁺, the water extract of Poria cocos Wolf protected against MPP⁺-induced neurotoxicity than those of Corni fructus extract. It is considered to be a potential functional material with antioxidant, anti-inflammatory and neuronal protective effect against to oxidative stress according to the extract methods of extracting Poria cocos Wolf and Corni fructus.

Purpose: Maximizing human comfort in design of medical environments depends immensely on specialized architects particularly critical care design; the study proposes Evidence-Based Design as an apparent analog to Evidence-Based Medicine. Healthcare facility designs are substantially based on the findings of study in an effort to design environments that augment care by improving patient safety and being therapeutic. On SPSS (Statistical Package for Social Science) t-test is applied to simulate two independent variables of PDR (Pre Design-Research) and POE (Post- Occupancy Evaluation). PDR is conducted on relatively new hospital Hallym University Dongtan Sacred Heart Hospital to analyse visibility from researchers' point of view, here the ICU is arranged in I-Shape. POE is applied on Dongguk University Ilsan Hospital to simulate walking on LogWare where two NS are designed based on L- Shape and Seoul St. Mary's Hospital, The Catholic University of Korea where five NS are functional for ICU Intensive Care Unit, Surgical Intensive Care Unit (SICU), Medical Intensive Care Unit (MICU), Critical Care Unit (CCU), Korean Oriental Medical Care Unit which are mostly arranged in U-Shape, and walking pattern is recognized to be in a zigzag path. Method: T-Test is applied on two dependent communication variables: walkability and visibility, with confidence interval of 95%. This study systematically analyses the Nurse Station (NS) typo-morphology, and simulates nurse horizontal circulation, by computing round route visits to patient's bed, then estimating minimum round route on LogWare stop sequence software. The visual connectivity is measured on depth map graphs. Hence the aim is to reduce staff stress and fatigue for better patients care by minimizing staff horizontal travel time and to facilitate nurse walk path and support space distribution by increasing effectiveness in delivering care. Result: Applying visibility graph and isovist field on space syntax on I- Shape, L- Shape and U- Shape ICU (SICU, MICU and CCU) configuration, I-shape facilitated 20% more patients in linear view as they stir to rise from their beds from nurse station compared to U-shape. In conclusion, it was proved that U-Shape supply minimum walking and maximum visibility; and L shape provides just visibility as the nurse is at pivot. I shape provides panoramic view from the Nurse Station but very rigorous walking.

To develop a functional drink using abalone, two abalone composites (APM-1, APM-2) were prepared by mixing the abalone and natural plants (Lycii fructus and Rubus coreanus Miq.). Their antioxidant and anti-fatigue effects were evaluated using rats running on a treadmill after 4 weeks supplementation of the abalone composites. Experimental groups were divided into four groups including normal (non-exercised group), control (exercised group), one dose per day (EAPM-1), and three doses per day (EAPM-2) with exercise by running. Antioxidant activities, and total phenols and flavonoids contents of APM-2 were significantly higher than those of APM-1 (p<0.05). Total lipid content in serum of EAPM-2 was significantly lower than that of control group (p<0.05). Lactate dehydrogenase activity and blood urea nitrogen content of EAPM-1 and EAPM-2 groups were significantly lower than that of control group. There were no significant difference in aspartate aminotransferase activity among control, EAPM-1 and EAPM-2 groups. In the meanwhile, alanine aminotransferase and alkaline phosphatase activities were significantly lower than that of control group. In serum and liver tissues of EAPM-1 and EAPM-2 groups, lipid peroxide contents significantly decreased compared to control group. DPPH radical scavenging activities in liver tissues of EAPM-1 and EAPM-2 groups were significantly higher than those of control group. Therefore, abalone composites were effective for the alleviation of oxidative stress caused by treadmill running, which was dependent on antioxidant activity and phenolic compounds content.

Morinda officinalis (MO) is a oriental medicinal herb which has been used traditionally for the treatment of impotence, anti-inflammatory, menstrual irregularity action and various brain diseases including antidepressant and anti-stress. In order to examine the mechanism of anticonvulsive effect, we treated the methanol extract of MO (100, 200 mg/kg, P.0) to the sleeping time and pentylenetetrazol (PTZ)-induced convulsive mice. The methanol extract of MO prolonged sleep time by pentobarbital. Dose-dependent of methanol extracts of MO were effected the concentration of GABA and GABA-T activity in the brain of PTZ-induced mice. Methanol extracts of MO significantly inhibited the convulsion state as well as the level of lipid peroxidation in the brain. The butanol and dichloromethane fraction of methanol extracts among the others effectively inhibited in vitro lipid peroxidation dose dependently ($5.0{\times}10^{-2}{\sim}20.0{\times}10^{-2}g/ml$).
